 (USPTO) specifies the size of the sheet on which the drawing is made, the type of paper, the margins, and other details relating to the making of the drawing. The reason for specifying the standards in detail is that the drawings are printed and published in a uniform style when the patent issues, and the drawings must also be such that they can be readily understood by persons using the patent descriptions.

No names or other identification are permitted within the “sight” of the drawing, and applicants are expected to use the space above and between the hole locations to identify each sheet of drawings. This identification may consist of the attorney’s name and docket number or the inventor’s name and application number and may include the sheet number and the total number of sheets filed (for example, “sheet 2 of 4”). The following rule, reproduced from title 37 of the Code of Federal Regulations, relates to the standards for drawings:

The United States patent law was revised in 1793. It stated that the Commissioner of the USPTO could ask for additional information, drawings, or diagrams if the description is not clear. By then, the rate of patent grants had grown to about 20 per year and the time burden on the Secretary of State was considered to be too burdensome. Patent applications were no longer examined. Patents were granted simply by submitting a written description of an invention, a model of the invention, if appropriate, and paying a fee of $30 then, and now $1000 in 2006 US dollars.

Drawings and photographs

In utility and design patent applications, drawings can be in black ink

s are not ordinarily permitted in utility and design patent applications, unless this is the only practicable medium for illustrating the claimed invention. For example, photographs of electrophoresis gels, blots, autoradiographs, cell cultures, histological tissue cross sections, animals, plants, in vivo imaging, etc. Color photographs can be accepted in utility and design patent applications if the conditions for accepting color drawings and black and white photographs have been satisfied.
